मैं हाइबरनेट उपयोग करने के लिए एक वर्ग है कि इस तरह दिखता है लागू करने के लिए कोशिश कर रहा हूँ नहीं मिल सकता है: निम्नलिखितहाइबरनेट डिफ़ॉल्ट tuplizer का दृष्टांत करने में असमर्थ गेटर
public class Item implements Serializable, Comparable<Item> {
// Item id
private Integer id;
// Description of item in inventory
private String description;
// Number of items described by this inventory item
private int count;
//Category item belongs to
private String category;
// Date item was purchased
private GregorianCalendar purchaseDate;
public Item() {
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public int getCount() {
return count;
}
public void setCount(int count) {
this.count = count;
}
public String getCategory() {
return category;
}
public void setCategory(String category) {
this.category = category;
}
public GregorianCalendar getPurchaseDate() {
return purchaseDate;
}
public void setPurchasedate(GregorianCalendar purchaseDate) {
this.purchaseDate = purchaseDate;
}
मेरे हाइबरनेट मैपिंग फ़ाइल शामिल:
<property name="puchaseDate" type="java.util.GregorianCalendar">
<column name="purchase_date"></column>
</property>
जब मैं दौड़ने की कोशिश करता हूं, तो मुझे त्रुटि संदेश मिलते हैं जो खरीद के लिए कोई गेटर फ़ंक्शन नहीं है दिनांक:

मैं हाइबरनेट के लिए नया हूं, इसलिए मुझे सभी इंस और आउट्स नहीं पता हैं, लेकिन मेरे पास buyDate विशेषता के लिए गेटटर और सेटर है। मुझे नहीं पता कि मैं यहाँ क्या खो रहा हूं - क्या कोई और करता है?
ठीक है, मैं मैं कुछ बेवकूफ याद आ रही थी पता था। बहुत बहुत धन्यवाद! – ZeldaPinwheel
मुझे एक सेटटर पर ऊंट के साथ एक ही समस्या थी। समस्या फिक्स्ड। –
मुझे एक ही समस्या थी - यह विशेष त्रुटि संदेश पहले * एक और * कह रहा था कि मेरे पास गेटर/सेटर्स सेटअप सही नहीं था ... – rogerdpack
